About this item
About this item
- Selectable Wattage & Output: Field-select 50W, 40W, or 30W at the fixture via onboard switch — delivers up to 7,323 lumens at up to 151 lm/W peak efficacy. No rewiring required.
- Wet Location & IP Rating: UL Listed for wet locations with IP66 ingress protection and NEMA 4X corrosion resistance — rated for direct water exposure, washdown hose-down, and outdoor or covered wet environments. Cold-start rated to −40°F (−40°C).
- Selectable CCT: Onboard switch adjusts between 3500K, 4000K, and 5000K at the fixture — no re-ordering required for different color temperature specifications.
- Integrated Microwave Occupancy Sensor: Built-in microwave (MVS) sensor — max mounting height 50 ft., detection range 50 ft. diameter. Detects motion through non-metallic partitions; ideal for higher ceilings and irregular spaces.
- DLC Listed & Rebate Eligible: DLC Listed under multiple categories including Low-bay Commercial & Industrial — qualifies for utility rebate programs in most U.S. markets. NSF Certified for food-safe environments.
